ABSTRACT

BACKGROUND: Jordan has experienced several COVID-19 waves in the past 2 years. Cross-sectional studies have been conducted to evaluate distress in healthcare practitioners (HCPs), but there is limited evidence with regards to the impact of continuing pandemic waves on levels of distress in HCPs. We previously studied psychological distress in HCPs during the start of the pandemic (period 1, when cases were infrequent and the country was in lockdown), and demonstrated that HCPs were experiencing considerable stress, despite the country reporting low caseloads at the time. In this study, we sought to utilize the same methodology to reexamine levels of distress as COVID-19 peaked in the country and HCPs began managing large numbers of COVID-19 cases (period 2). METHODS: A cross-sectional online survey utilizing a tool previously used during period 1 was completed by HCPs working in various settings. Demographic, professional and psychological factors such as distress, anxiety, depression, burnout, sleep issues, exhaustion, and fear were assessed; and coping strategies also were measured. Items in the tool were assessed for reliability and validity. A multivariable regression was used to identify factors that continued to impact distress during period 2. RESULTS: Samples in both periods (n = 937, n = 876, respectively) were relatively comparable in demographic characteristics, but in period 2, a greater proportion of nurses and healthcare practitioners reported working in general hospitals. During the pandemic peak (period 2), 49.0% of HCPs reported high levels of distress (compared to 32% in period 1); anxiety and depression scores were approximately 21% higher in period 2; and 50.6% reported fatigue (compared to 34.3% in period 1). Variables significantly associated with greater distress in period 2 included experiencing burnout, experiencing sleep disturbances, being fatigued, having fatalistic fears, and having fears related to workload. Conversely, being male, reporting satisfaction at work, and using positive coping practices were associated with a significantly lower odds of being in distress. CONCLUSIONS: Between the two periods (early pandemic and first wave), COVID-19-related mental health continued to deteriorate among HCPs, highlighting the need to do more to support HCP front-liners facing COVID-19 surges.

ABSTRACT

BACKGROUND: Though sepsis is common in patients with cancer, there are limited studies that evaluated sepsis and septic shock in this patient population. The objective of this study was to evaluate the outcomes and to identify predictors of mortality in cancer patients admitted to the intensive care unit (ICU) with septic shock. METHODS: This was a retrospective study conducted at a medical-surgical oncologic ICU of a comprehensive cancer center. Adult cancer patients admitted with septic shock between January 1, 2008 and December 31, 2019 were enrolled. Septic shock was defined as an ICU admission diagnosis of sepsis that required initiating vasopressors within 24 h of admission. Patient baseline characteristics, ICU length of stay and ICU and hospital mortality were recorded. Univariate analysis and logistic regression were performed to identify predictors associated with ICU and hospital mortality. RESULTS: During the study period, 1408 patients met the inclusion criteria. The mean age was 56.8 ± 16.1 (SD) years and mean Acute Physiology and Chronic Health Evaluation (APACHE) II was 23.0 ± 7.91 (SD). Among the enrolled patients, 67.8% had solid tumors while the remaining had hematological malignancies. Neutropenia and thrombocytopenia were reported in 19.3 and 39.5% of the patients, respectively, and mechanical ventilation was required for 42% of the patients. Positive cultures were reported in 836 (59.4%) patients, most commonly blood (33%) and respiratory (26.6%). Upon admission, about half the patients had acute kidney injury, while elevated total bilirubin and lactic acid levels were reported in 13.8 and 65.2% of the patients, respectively. The median ICU length of stay was 4 days (IQR 3-8), and ICU and hospital mortality were reported in 688 (48.9%) and 914 (64.9%) patients, respectively. Mechanical ventilation, APACHE II, thrombocytopenia, positive cultures, elevated bilirubin and lactic acid levels were significantly associated with both ICU and hospital mortality. CONCLUSIONS: In a relatively large cohort of patients with solid and hematological malignancies admitted to the ICU with septic shock, hospital mortality was reported in about two-third of the patients. Mechanical ventilation, APACHE II, thrombocytopenia, positive cultures, elevated bilirubin and lactic acid levels were significant predictors of mortality.

ABSTRACT

BACKGROUND: Staging of non-small-cell lung cancer (NSCLC) is a multidisciplinary process involving imaging, endoscopic and surgical techniques. This study aims at investigating the diagnostic accuracy of 18F-FDG PET/CT, CT scan, and endobronchial ultrasound/transbronchial needle aspirate (EBUS/TBNA) in preoperative mediastinal lymph nodes (MLNs) staging of NSCLC. METHODS: We identified all patients who were diagnosed with NSCLC at the King Hussein Cancer Center in Amman, Jordan, between July 2011 and December 2017. We collected their relevant clinical, radiological, and histopathological findings. The per-patient analysis was performed on all patients (N = 101) and then on those with histopathological confirmation (N = 57), followed by a per-lymph-node-station basis overall, and then according to distinct N-stage categories. RESULTS: 18F-FDG PET/CT, in comparison to CT, had a better sensitivity (90.5% vs. 75%, p = 0.04) overall and in patients with histopathological confirmation (83.3% vs. 54.6%), and better specificity (60.5% vs. 43.6%, p = 0.01) overall and in patients with histopathological confirmation in MLN staging (60.6% vs. 38.2%). Negative predictive value of mediastinoscopy, EBUS/TBNA, and 18F-FDG PET/CT were (87.1%), (90.91%), and (83.33%) respectively. The overall accuracy was highest for mediastinoscopy (88.6%) and EBUS/TBNA (88.2%), followed by 18F-FDG PET/CT (70.2%). Dividing patients into N1 disease vs. those with N2/N3 disease yielded similar findings. Comparison between 18F-FDG PET/CT and EBUS/TBNA in patients with histopathological confirmation shows 28 correlated true positive and true negative findings with final N-staging. In four patients, 18F-FDG PET/CT detected metastatic MLNs that would have otherwise remained undiscovered by EBUS/TBNA alone. Lymph nodes with a maximal standardized uptake value (SUVmax) more than 3 were significantly more likely to be true-positive. CONCLUSION: Multimodality staging of the MLNs in NSCLC is essential to provide accurate staging and the appropriate treatment. 18F-FDG PET/CT has better overall diagnostic utility when compared to the CT scan. The NPV of 18F-FDG PET/CT in MLNs is reliable and comparable to the NPV of EBUS/TBNA. SUVmax of MLNs can help in predicting metastases, but nevertheless, a positive 18F-FDG PET/CT MLNs particularly if such a result would change the treatment plan, should be verified histopathologically.

ABSTRACT

PURPOSE: Limited studies evaluated the predictive value of serum lactate (LA) in critically ill patients with cancer. The main objective of this study was to evaluate the predictive validity of LA single measurements as well as LA clearance in predicting mortality in patients with cancer having septic shock. The study also aimed to determine the LA measurement over the first 24 hours with the highest predictability for hospital mortality. MATERIALS AND METHODS: A retrospective cohort study of adult patients with cancer having septic shock and LA measurements during the first 24 hours. Three receiver-operating characteristic (ROC) curves were constructed to evaluate the predictive validity for hospital mortality of LA at baseline, at 6 hours and at 24 hours after identifying septic shock. The ROC with the largest area under the curve was analyzed to determine LA level with the highest predictability for hospital mortality. In addition, the ability of LA normalization (LA <2 mmol/L at 6 hours and at 24 hours) and the degree of LA elimination (>10% and >20% at 24 hours) to predict hospital mortality were evaluated by determining the predictive values for each clearance end point. RESULTS: The study included 401 patients. LA >2.5 mmol/L at 24 hours showed the largest area under the ROC curve to predict hospital mortality (ROC area: 0.648; 95% confidence interval: 0.585-0.711) with a sensitivity of 58.4% and specificity of 62.8%. The LA normalization, LA clearance >10%, and LA clearance >20% were also predictors of hospital mortality, with the highest sensitivity for LA normalization at 6 hours (74%) and LA normalization at 24 hours (73.4%). CONCLUSION: In patients with cancer having septic shock, LA >2.5 mmol/L at 24 hours of septic shock had the highest predictability for hospital mortality. The LA normalization and clearance were also predictors of hospital mortality. However, all LA end points were not strong predictors.

ABSTRACT

This study aims to enable effective breast ultrasound image classification by combining deep features with conventional handcrafted features to classify the tumors. In particular, the deep features are extracted from a pre-trained convolutional neural network model, namely the VGG19 model, at six different extraction levels. The deep features extracted at each level are analyzed using a features selection algorithm to identify the deep feature combination that achieves the highest classification performance. Furthermore, the extracted deep features are combined with handcrafted texture and morphological features and processed using features selection to investigate the possibility of improving the classification performance. The cross-validation analysis, which is performed using 380 breast ultrasound images, shows that the best combination of deep features is obtained using a feature set, denoted by CONV features that include convolution features extracted from all convolution blocks of the VGG19 model. In particular, the CONV features achieved mean accuracy, sensitivity, and specificity values of 94.2%, 93.3%, and 94.9%, respectively. The analysis also shows that the performance of the CONV features degrades substantially when the features selection algorithm is not applied. The classification performance of the CONV features is improved by combining these features with handcrafted morphological features to achieve mean accuracy, sensitivity, and specificity values of 96.1%, 95.7%, and 96.3%, respectively. Furthermore, the cross-validation analysis demonstrates that the CONV features and the combined CONV and morphological features outperform the handcrafted texture and morphological features as well as the fine-tuned VGG19 model. The generalization performance of the CONV features and the combined CONV and morphological features is demonstrated by performing the training using the 380 breast ultrasound images and the testing using another dataset that includes 163 images. The results suggest that the combined CONV and morphological features can achieve effective breast ultrasound image classifications that increase the capability of detecting malignant tumors and reduce the potential of misclassifying benign tumors.

ABSTRACT

BACKGROUND: In Jordan, four non-graphic pictorial health warning labels (PHWLs) concerning a limited selection of tobacco-caused harms have been used since 2011; however, research suggests that they may be ineffective. OBJECTIVES: To explore Jordanian smokers' reactions to novel PHWLs featuring various health themes and/or graphic and symbolic imagery and to discuss existing PHWLs in light of the novel PHWLs. METHODS: We conducted 14 focus groups (FGs) with smokers who assessed 12 novel PHWLs and commented on four existing PHWLs. Data were analysed using an inductive approach. RESULTS: Six themes emerged from the FG discussions: understanding the overall meaning of PHWLs, the impact of graphic images, magnitude and controllability of harm, personal or vicarious experiences, the futility of quitting and fatalism. PHWLs depicting graphic respiratory and oral tobacco-caused harms resonated with most smokers. Smokers also sought direct, harm-specific taglines when trying to understand the overall PHWL. Some smokers viewed the PHWLs as exaggerated, and while the majority acknowledged that smoking was harmful, they felt that PHWLs would not accomplish their goal of inducing quitting. CONCLUSIONS: Our findings support the use of graphic imagery to communicate tobacco-caused harms (particularly respiratory ones) and the use of specific taglines explaining the mechanism of harm depicted.

ABSTRACT

BACKGROUND: Pictorial warning labels (PWLs) deter initiation and motivate quitting. Assessing PWLs is important to track effectiveness and wear out. Jordan introduced an updated set of PWLs in 2013. This study assessed the effectiveness of the set after 2.5 years on the market. METHODS: We administered a survey in a cross-sectional sample of young adults aged 17-26 years. For convenience, respondents were recruited on university campuses. For heterogeneity, respondents were solicited from the different schools in four geographically diverse university campuses. The study compared perceptions of effectiveness surveyed in 2015 to perceptions gauged in 2010 during a pre-launch evaluation exercise. Outcomes of interest were: salience, fear evocation, adding information, and ability to motivate quitting smoking (for smokers) or deterring starting (for non-smokers). RESULTS: Results indicate awareness of the set among smokers and non-smokers, and their recall of at least one PWL message. Results also indicate effectiveness of the set: (1) 1/3 smokers who frequently saw them reported PWLs to trigger considering quitting, (2) and among both smokers and non-smokers the set in 2015 sustained ability to motivate quitting and staying smoke-free. However, results uncover erosion of salience, suggesting that the set has reached its end of life. Finally, results reveal variability in performance among PWLs; the one PWL that depicts human suffering significantly outperformed the others, and its ability to motivate was most strongly associated with its ability to evoke fear. CONCLUSION: Based on the early signs of wear-out (i.e. erosion of salience), and understanding the importance of sustaining upstream outcomes (especially fear evocation) to sustain motivation, we recommend retiring this set of PWLs and replacing it with a stronger set in line with proven standards.

ABSTRACT

News media play a critical role in tobacco control. To strengthen this role in Jordan, four newspapers were searched and 1 145 articles between 2011 and 2015 were coded for mention of MPOWER topics and for tone of coverage (neutral, pro-, or anti-tobacco control). Monthly counts, mention of tobacco control topics and the tones were examined. The monthly count of tobacco control-related news items showed an upward trend with an average monthly growth of 16%. Peaks in coverage were observed in synchrony with national tobacco control developments. 'Warn' was the topic most frequently mentioned (46%). 'Protect' was the only topic that showed a statistically significant upward trend over time. A pro-tobacco control tone was more prevalent than an antitobacco control or neutral tone. Thus, efforts are needed to enhance the newsworthiness of certain topics, boost influence on decision-makers and pre-empt industry interference.

ABSTRACT

OBJECTIVE: To identify factors predictive of admission of patients with cancer to an ICU. In addition, the study aimed to describe the characteristics and outcomes, both short-term and long-term, of patients with cancer admitted to the ICU. DESIGN: Retrospective case-control study, utilizing the institution's cancer registry. SETTING: Comprehensive cancer center. PATIENTS: Patients with cancer. The case group consisted of patients who required ICU admission during the study period, whereas the control group consisted of patients who did not require ICU admission. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The patient characteristics and outcomes were recorded. Univariate and multivariate analyses were conducted to determine factors associated with ICU admission. The registry included 10,792 patients, and among those, 2,439 patients (22.6%) required ICU admission after a median of 10.1 months (interquartile range, 3.28-25.2). The following factors were associated with ICU admission: hematologic malignancy (odds ratio, 1.51; 95% CI, 1.26-1.81), chemotherapy (odds ratio, 1.74; 95% CI, 1.48-2.03), advanced cancer (odds ratio, 2.57; 95% CI, 1.44-4.60), and smoking (odds ratio, 1.38; 95% CI, 1.20-1.61). The most common ICU admission diagnoses were sepsis (21.5%) and respiratory insufficiency/failure (25.7%). The ICU mortality was 36.5%, whereas the 1-year and 5-year survival rates were 22.8% and 14.2%, respectively. CONCLUSION: In a comprehensive cancer center, about one fourth of the patients required ICU admission. Addressing modifiable risk factors associated with ICU admission is essential to potentially reduce ICU admissions and improve long-term survival.

ABSTRACT

PURPOSE: To evaluate the effectiveness and safety of hydrocortisone (HC) in cancer patients with septic shock. METHODS: This was a retrospective study of adult cancer patients with septic shock who received low-dose HC therapy (200 mg/day). The effectiveness of HC was assessed by determining the proportion of patients with reversal of septic shock, time to reversal, and mortality. The safety was assessed by determining the incidences of hyperglycemia, hypernatremia, and secondary infections, using a case-control approach. RESULTS: During the study period, 96 patients were enrolled. Reversal of septic shock was reported in 46 (47.9%) patients, median time to reversal was 1.9 days (range 0.2-7.6), ICU mortality was reported in 62 (65.26%) patients, and 28-day mortality in 64 (66.7%) patients. The incidence of secondary infections was higher in patients who received HC therapy, compared to patients who did not receive HC during septic shock: 44.8% vs 27.4%, P = 0.028. CONCLUSIONS: HC therapy was associated with resolution of septic shock in about half of the patients and a high incidence of secondary infections. Prospective studies are needed to fully assess the efficacy and safety of HC in cancer patients with septic shock.

ABSTRACT

AIM: To quantify the economic burden associated with tobacco smoking among smokers aged 30-69 years, and second-hand smokers (SHS) aged 15-69 years in Jordan. MATERIALS AND METHODS: A prevalence-based analysis was conducted in alignment with the Economics of Tobacco Toolkit developed by the WHO. The time-horizon of the analysis was one year (2019). Direct and indirect costs were estimated using data from the 2019 Global Burden of Diseases study. The analysis targeted the Jordanian population of smokers aged 30-69 years, and SHS aged 15-69 years. Adjustments were applied for age, gender, and smoking-related diseases. Direct costs were estimated using the smoking-attributable fraction (SAF) and national health expenditures. Indirect costs were divided into morbidity and mortality components. A discount rate of 3.0% and an annual productivity growth rate of 1.0% were assumed in modelling future economic losses. A sensitivity analysis was conducted on the lower and upper estimates of data used in this study. RESULTS: The cost of tobacco smoking and SHS exposure was estimated at US$2,108 million (95% confidence interval [CI] = US$2,003 million-US$2,245 million). This represents 4.7% (95%CI = 4.5%-5.0%) of national gross domestic product (GDP). Direct costs accounted for 3.1% of national GDP. Tobacco smoking accounted for 85.0% of total cost and SHS exposure accounted for 15.0% of total cost. Direct costs accounted for 67.0% of total cost, while indirect morbidity and mortality costs accounted for 9.0% and 24.0% of total cost, respectively. Non-communicable diseases accounted for 96.0% of total direct costs compared to communicable diseases (4.0% of total direct costs). CONCLUSIONS: Smoking cessation interventions such as raising taxes on cigarettes, protecting people from tobacco smoke, warning labels, plain packaging, and bans on advertising, are crucial for controlling national expenditures for treating smoking-related diseases and for averting future economic losses.


In this work, we aimed to calculate the annual economic impact of tobacco smoking in Jordan in 2019. We used the World Health Organization toolkit methodology to estimate both the direct and indirect costs associated with smoking nationally. Our focus was on Jordanian smokers aged 30-69 years and people exposed to second-hand smoke aged 15­69 years. Direct costs were calculated using epidemiological data on the proportion of health expenditures attributable to smoking and the national health expenditures. Indirect costs were divided into two components: morbidity and mortality. We also projected future economic losses, assuming a 3.0% discount rate and a 1.0% annual growth rate of productivity. Our study estimated that the cost of smoking and exposure to second-hand smoke was US$2,108 million (US$2,003 million-US$2,245 million), which accounted for 4.7% (4.5%-5.0) of Jordan's gross domestic product. The majority of the cost (85.0%) was due to direct smoking, while 15.0% was due to exposure to second-hand smoke. Direct costs made up 67.0% of the total cost, while the costs related to morbidity and mortality accounted for 9.0% and 24.0% of the total cost, respectively. In conclusion, our study emphasized that tobacco smoking has a significant economic impact on Jordan. Therefore, it is crucial to implement effective smoking cessation programs, such as enforcing existing anti-tobacco policies and raising taxes. These measures can help control national expenditures for treating smoking-related diseases and prevent future economic losses.

ABSTRACT

CONTEXT: Waterpipe tobacco smoking (WTS) has gained popularity, but its physiologic effects have not been extensively studied: rather, studies have focused on WTS's chronic effects or have evaluated limited respiratory/cardiac parameters. OBJECTIVE: We sought to characterize in a more detailed manner the acute effects of WTS on lung function and exercise capacity. METHOD: We recruited 24 healthy WTS males. We used a pilot single-group pre-test (abstained from WTS for ≥48 h) post-test (within 0.5 h of a 45-min WTS session) design. We performed spirometry, diffusing lung capacity and time-limited CPE testing (CPET; cycloergometer; 2-min 20-Watt warm-up and 25-Watt increase every 2-min for 10 min). RESULTS: Mean age was 20.4 years; Post-WTS, the following significant changes were observed: CO level increased from 3.7 ppm to 24.4; oxygen consumption decreased (from 1.86 L/min to 1.7); baseline respiratory rate increased (from 17.7 breath/min to 19.7); forced expiratory flow over the middle half of the forced vital capacity decreased (from 5.51 L to 5.29); and perceived exertion (measured by Borg scale) at mid and peak exercise increased. Baseline resting systolic blood pressure, pulse pressure, and pulse pressure product increased post-WTS (from 118.9 mmHg to 129.2; from 45.3 mmHg to 55.6; and from 9.9 mmHg/min to 11.1 post-WTS, respectively). During exercise, a decrease in oxygen pulse was observed post-WTS (from 10.89 ml/beat to 9.97), while the heart rate-oxygen consumption relationship increased post-WTS (from 3.52 beats/ml/kg to 3.91). CONCLUSION: Acute WTS appears to induce impairment in lung function and exercise capacity. Larger studies are warranted to further characterize the nature and extent of such impairment.

ABSTRACT

PURPOSE: Describe the incidence, characteristics and cost of adverse drug events that necessitate admission to the intensive care unit in oncology patients. METHODS: This was a prospective observational 5-months study at a medical/surgical intensive care unit of a comprehensive teaching cancer center. Patients admitted to the intensive care unit were screened to determine whether the admission was due to an adverse drug event. The adverse drug events were characterized based on the suspected medication, system involved and preventability. Patient demographics, length of stay, mortality and the total patient charges during their intensive care unit stay were recorded. RESULTS: During the study period, 249 patients were screened and an adverse drug event was the primary cause of 57 (22.9%) admissions. The most common medications associated with an adverse drug event requiring intensive care unit admission were antineoplastics (n = 37), analgesics (n = 9) and anticoagulants (n = 4). Ten adverse drug events were considered preventable. The average length of stay for patients with adverse drug events resulting in intensive care unit admission was 6.2 days ±9.8 (SD) and the mortality rate was 28.1%. Hematological malignancy was independently associated with adverse drug events resulting in intensive care unit admission. The average patient charges for the intensive care unit stay was US$11,692 ± 17,529 (SD), which corresponded to about US$1.5 million in annual patient charges for a 12-bed intensive care unit at a cancer institution. CONCLUSIONS: Adverse drug events resulting in intensive care unit admission in oncology patients are common and often associated with significant morbidity, mortality, and cost.

ABSTRACT

Background: Early in the coronavirus disease 2019 (COVID-19) pandemic, hydroxychloroquine (HCQ) drew substantial attention as a potential COVID-19 treatment based on its antiviral and immunomodulatory effects in vitro. However, HCQ showed a lack of efficacy in vivo, and different groups of researchers attributed this failure to the insufficient drug concentration in the lung following oral administration (HCQ is only available in the market in the tablet form). Delivering HCQ by inhalation represents a more efficient route of administration to increase HCQ exposure in the lungs while minimizing systemic toxicity. In this pilot study, the safety, tolerability, and pharmacokinetics of HCQ nebulizer solution were evaluated in healthy volunteers. Methods: Twelve healthy participants were included in this study and were administered 2 mL of HCQ01 solution (equivalent to 25 mg of HCQ sulfate) through Aerogen® Solo, a vibrating mesh nebulizer. Local tolerability and systemic safety were assessed by forced expiratory volume in the first and second electrocardiograms, clinical laboratory results (e.g., hematology, biochemistry, and urinalysis), vital signs, and physical examinations. Thirteen blood samples were collected to determine HCQ01 systemic exposure before and until 6 hours after inhalation. Results: The inhalation of HCQ01 was well tolerated in all participants. The mean value of Cmax for the 12 participants was 9.66 ng/mL. Tmax occurred at around 4.8 minutes after inhalation and rapidly decreased thereafter. The reported systemic exposure was very low with a mean value of 5.28 (0.6-15.6) ng·h/mL. Conclusion: The low systemic concentrations of HCQ01 of 9.66 ng/mL reported by our study compared with 1 µg/mL previously predicted after 200 mg BID oral administration, and the safety and tolerability of HCQ01 administered as a single dose through nebulization, support the assessment of its efficacy, safety, and tolerability in further studies for the treatment of COVID-19.

ABSTRACT

BACKGROUND: There is a scarcity of evidence regarding the real-world effectiveness of coronavirus disease 2019 (COVID-19) vaccines. This was the first study to evaluate the effectiveness of four types of vaccines against asymptomatic and symptomatic infection, and COVID-19 outcomes among the general population. METHODS: This was a matched comparison group quasi-experimental study conducted in Jordan between 1 January and 29 August 2021. In the first part of the study, 1200 fully vaccinated individuals were matched with 1200 unvaccinated control participants. In order to measure vaccine effectiveness, the infection rates of both vaccinated and unvaccinated groups were calculated. The second part of the study included measuring specific anti-SARS CoV-2 immune cells and antibodies. RESULTS: BNT162b2 (Pfizer, New York, NY, USA) showed a significantly higher effectiveness against asymptomatic COVID-19 infection (91.7%) and hospitalization (99.5%) than BBIBP-CorV (Sinopharm, Beijing, China) (88.4% and 98.7%, respectively) and ChAdOx1 nCoV-19 (AstraZeneca, Cambridge, UK) (84.3%, and 98.9%, respectively). The effectiveness rates of the Sputnik V (Gamaleya Research Institute, Moscow, Russia) vaccine against asymptomatic, symptomatic, and hospitalization were 100%, 100%, and 66.7%, respectively. The highest median anti-spike (S) IgG values were seen in individuals who received BNT162b2 (2.9 AU/mL) and ChAdOx1 nCoV-19 (2.8 AU/mL) vaccines. The levels of anti-S IgG were significantly decreased after 7 months of vaccination with BNT162b2 and BBIBP-CorV. There were significant decreases in the median number of neutralizing antibodies one month and seven months after receiving BNT162b2 (from 88.5 to 75.2 4 Bioequivalent Allergen Unit per milliliter/mL), BBIBP-CorV (from 69.5 to 51.5 BAU/mL), and ChAdOx1 nCoV-19 (from 69.2 to 58.BAU/mL) vaccines. The highest percentage of T cells specific to COVID-19 vaccine was found in individuals who received BNT162b2 (88.5%). CONCLUSION: All four vaccines evaluated in this study showed effectiveness against asymptomatic COVID-19 infection, symptomatic infection, hospitalization, and death. Furthermore, BNT162b2, BBIBP-CorV, and ChAdOx1 nCoV-19 induced high levels of immunology markers within one month of vaccination.

ABSTRACT

This case study highlights how a looming health crisis was leveraged as drivers for positive change for the health sector, in line with the health security agenda. In Jordan, several authorities are mandated by law to manage health emergencies. Following the declaration of outbreaks of cholera in Iraq, Lebanon and Syria, health authorities in Jordan called for a series of emergency meetings during September 2022 to discuss implications around travel and trade as well as shared waters. WHO was part of the consultations and provided guidance on the application of the International Health Regulations 2005. As the risk for cholera importation persisted, the Ministry of Health assumed its leadership role for the overall health sector response while the Jordanian Center for Disease Control assumed a coordinating function. Roles and responsibilities were enshrined in the National Cholera Preparedness and Response Plan. In consideration of the vulnerability of refugee camps and settlements towards Cholera, the existing Jordan humanitarian coordination platforms such as the Health Sector Working Group were used to share information and to coordinate activities. A whole-of-government risk assessment during December 2022 was complemented by a field visit at Zaatari refugee camp. This helped assess the risk and readiness for a cholera outbreak in Jordan and informed priority activities, such as the establishment of a national risk communication and community engagement working group as well as training on case management.

ABSTRACT

BACKGROUND: Failure to quit smoking in cancer patients is associated with the development of a second primary tumor and a suboptimal response to chemotherapy. However, data characterizing cancer patients' ability to quit is scarce, particularly in developing countries. Such information is valuable in highlighting the potential of cessation interventions in countries where smoking rates are high and antismoking policies are not yet fully implemented. OBJECTIVES: To measure the abstinence rates and identify reasons for the failure to quit smoking in patients visiting a smoking cessation clinic in a comprehensive cancer center in Jordan. METHODS: Through retrospective medical chart review and prospective follow-up by phone, we studied long-term abstinence rates and reasons for the failure to quit smoking in 156 cancer patients referred to the smoking cessation clinic to receive counseling and pharmacological treatment. Patient demographics, clinical and smoking characteristics and long-term abstinence at 12 months were recorded, as were reasons for the failure to quit smoking. RESULTS: The 12-month abstinence rate was 21.2%. The main reasons for failing to quit smoking included personal or professional stressful situations, not being able to handle withdrawal and the belief that quitting had no value. CONCLUSION: Abstinence rates in Jordanian cancer patients fall at the lower end of the range that has been reported in the literature for cancer patients. Efforts to improve these rates should focus on assisting patients in handling stress, and in adjusting medications to improve withdrawal symptoms.

ABSTRACT

The objectives were to determine the rate of cigarette smoking and correlates of its use among a sample of Jordanian adults (N = 600). A survey-based, cross-sectional study was conducted with a convenient sample. Logistic regression was used to determine predictors of being a cigarette smoker. Approximately half of the population (45%) had smoked a cigarette in the past month, 40% in the past week, and 36% in past 24 hours. These findings underscore the magnitude of the smoking problem in the Jordanian population and the urgent need for effective interventions. Future research should focus on developing interventions that incorporate the predictors identified.

ABSTRACT

Continued smoking in cancer patients is commonly observed in Jordan. In a country that exhibits some of the highest smoking rates globally, enhancing patient education regarding the value of smoking cessation for cancer care is vital. The objectives of our study were to describe sociodemographic and clinical factors associated with continued smoking in Jordanian smokers after a cancer diagnosis; to identify reasons for smoking and knowledge regarding smoking's impact on care; to examine in a multivariable manner the factors associated with continued smoking, and to accordingly generate patient counseling recommendations. An interviewer-administered survey using the Theoretical Domains Framework was employed. Among 350 subjects (mean age 51.0, median 52.7), approximately 38% of patients had quit or were in the process of quitting; 61.7% remained smokers. Substantial knowledge gaps with regard to the impact of continued smoking on cancer care were observed. Remaining a smoker after diagnosis was associated with being employed, not receiving chemotherapy or surgery, having lower confidence in quitting, and having a lower number of identified reasons for smoking. Interventions to promote cessation in Jordanian cancer patients who smoke should focus on enhancing patient awareness about the impact of smoking in cancer care and raising perceived self-efficacy to quit.

ABSTRACT

OBJECTIVES: To describe quitting experiences of cancer patients in a Cancer Center in Jordan; to study patients' perceptions regarding the process of smoking cessation; and to provide insights about patients in this difficult setting in order to inform oncology practitioners with regards to how improve perceptions and skills related to quitting. METHODS: An Arabic cross-sectional questionnaire was developed to evaluate smoking and quitting behaviors in the context of cancer. The tool used as its framework the Theoretical Domains Framework to capture quitting perceptions of cancer patients who smoke, as well as social, environmental, and system-level factors that influence quitting. Eligible patients who were treated at the Center (both in-patient and out-patient settings) and who were current smokers or who smoked up to the time of cancer diagnosis were eligible. Patients were interviewed between July, 2018 and January 2020 using two versions of the questionnaire: an 'ex-smokers' version, and a 'current smokers' version. RESULTS: Only a third of subjects (104/350) had been smoke-free for at least 30 days. Both smokers and ex-smokers generally felt that quitting was important, but mean importance and confidence scores (out of 10) were significantly lower in current smokers (8.2 versus 9.1, p-value=0.002; 6.4 versus 8.7, p-value=0.000). Roughly 31% of subjects believed smoking harms were exaggerated and that smoking was not an addiction. About 62% of subjects agreed quitting required skills, and 78.5% felt the steps to quit were clear, but across several listed strategies for quitting, use of these was limited (even in ex-smokers). Among current smokers, roughly a third exhibited forms of cessation fatigue. CONCLUSION: Jordanian cancer patients who smoke present with limited knowledge about the quitting process. Even when some success is observed, low rates of utilization of specific quitting strategies were observed, highlighting the need for better counseling about quitting.
